Meris Mercury 7 Review

An elegant ambient reverb machine with powerful sound-shaping capabilities.

Inspired in part by the legendary Lexicon 224 reverb (a unit made famous by, among other things, the Blade Runner soundtrack), the Meris Mercury 7 is a formidable algorithmic DSP reverb. Once only available as a mono rack module, the Mercury 7 is now available in a stereo pedal format. In this more compact pedal package it’s easy to use the Mercury7 as a conventional reverb pedal, but that would be a little like buying an iPad to use its clock. This is a very deep and capable reverb machine.

You can make very profound changes in the balance that make pitch effects stronger, less organic, and more reminiscent of
movie sound design.

Diving Deep
The Mercury7’s control panel hints at the unit’s power. But the control layout is elegant and relatively spare compared to some high-power DSP reverbs. There are six knobs (space delay, modulate, mix, lo frequency, pitch vector, and hi frequency) and two mini buttons: alt, which lets you access secondary functions and store sounds, and a selector for ultraplate or cathedra—the Mercury7’s two reverb algorithms. There are two footswitches for bypass and swell, and there’s also an expression pedal jack that can be used to control all parameters simultaneously. Needless to say, we can’t cover every aspect of this marvel in the space of a single review. But you don’t have to wander too far to find huge sounds within the Mercury7.


Amazing, studio quality sounds in a compact package.

Complex functions can be hard to use on the fly.

Space Sounds Abound
The pitch vector knob is the centerpiece of the control set, with settings for off, octave down, slight pitch down, slight pitch up, 5th up, and shimmer (which is an octave up). Factory balance settings for the basic pitch vector colors are excellent. But pressing the alt control as you move the mix knob lets you control how much of the pitch vector shift is present, and you can make very profound changes in the balance that make pitch effects stronger, less organic, and more reminiscent of movie sound design.

In the cathedra algorithm—with additions of shimmer pitch vector, low space decay settings, fast and deep modulation settings, and the mix all the way up—my guitar was transformed. The high mix reduced the intensity of my pick attack and the effect bloomed like clouds of sound—making the guitar feel more like some slow-motion organ than a 6-string. To more precisely shape the attack, you can press the alt button and adjust the level with the pitch vector knob. Within these ranges I could summon violin-like notes that were beautiful for haunting, slow, single-note melodies, and keyboard-like pads on open-voiced triads.

Moving the pitch vector to 5th up, I conjured ethereal sounds that evoked images of an underwater harp. When I jacked the space decay up, I got a creepy, wind-tunnel-like effect with a super-long trail that lifted chords into the ether. Another very cool thing about these extra-spacy tones is that it’s easy to maintain note articulation (if you need it) through use of the tone shaping controls. Even at extra-ambient settings, I could shape crisply defined individual notes with ample high end.

The Verdict
Textural guitarists will have a field day with the Mercury 7. And if you’re a sound sculptor and use reverb as one of your pedalboard tools, the Mercury 7 is worth deep investigation. The Mercury 7’s mind-boggling array of atmospheric sounds enables exploration of completely artificial sound designs, organic ambience, and unique voices that transform the guitar into another instrument entirely. Indeed, the Mercury 7 is itself more than a pedal effect: It’s a highly potent musical instrument that can crack open whole galaxies of sound.

It’s not difficult to replace the wiring in your pickups, but it takes some finesse. Here’s a step-by-step guide.

Hello and welcome back to Mod Garage. After numerous requests, this month we’ll have a closer look at changing wires on a single-coil pickup. As our guinea pig for this, I chose a standard Stratocaster single-coil, but it’s basically the same on all single-coil pickups and easy to transfer. It’s not complicated but it is a delicate task to not destroy your pickup during this process, and there are some things you should keep in mind.

The emotional wallop of the acoustic guitar sometimes flies under the radar. Even if you mostly play electric, here are some things to consider about unplugging.

I have a love-hate relationship with acoustic guitars. My infatuation with the 6-string really blasted off with the Ventures. That’s the sound I wanted, and the way to get it was powered by electricity. Before I’d even held a guitar, I knew I wanted a Mosrite, which I was sure was made of fiberglass like the surfboards the Beach Boys, Surfaris, and the Challengers rode in their off time. Bristling with space-age switchgear and chrome-plated hardware, those solidbody hotrod guitars were the fighter jets of my musical dreams. I didn’t even know what those old-timey round-hole guitars were called. As the singing cowboys Roy Rogers and Gene Autrey strummed off into the sunset, the pace of technology pushed the look and sound of the electric guitar (and bass) into the limelight and into my heart. Imagine my disappointment when I had to begin my guitar tutelage on a rented Gibson “student” acoustic. At least it sort of looked like the ones the Beatles occasionally played. Even so, I couldn’t wait to trade it in.

Need an affordable distortion pedal? Look no further.

We live in the golden age of boutique pedals that are loaded with advanced features—many of which were nearly unthinkable a decade or so ago. But there’s something that will always be valuable about a rock-solid dirt box that won’t break your wallet. Here’s a collection of old classics and newly designed stomps that cost less than an average concert ticket.
